Question
Chapter 47.3, Problem 4CC
Summary Introduction
To explain: The expected result, when zone of polarizing activity (ZPA) is removed from a limb bud and then a bead dripped in sonic hedgehog is placed in the center of the limb bud.
Concept introduction: The limb bud development is determined by two regions – the apical ectodermal ridge (AER) and the zone of polarizing activity (ZPA). The AER region determines the growth of a limb along the proximal-distal axis. The ZPA region determines the growth of the limb along the anterior-posterior axis.
